[AC-1194] Alloy 1.5 - Data Binding Enhancement not working

Upgraded to SDK 3.4.0, which comes with Alloy 1.5. According to Alloy 1.5 release notes: https://github.com/appcelerator/alloy/blob/1_5_X/CHANGELOG.md There are two data binding enhancements: Support mixture of text and data binding notation when binding model attributes to XML attributes, for example, . Support mapping multiple model attributes to a single XML attribute, for example, . I tested it with a collection, not a single model, like one of the examples here: http://docs.appcelerator.com/titanium/latest/#!/guide/Alloy_Data_Binding But, it just doesn't work.
